Sorry, we're a little late to the party. To answer some of the questions raised:
There are many different intake brands to choose from. What sets Airaid systems apart is overall fit and finish. Everything we build is application-specific and designed specifically for the vehicle. Also, we use a special blend of urethane for our filter casings, while most other filters are constructed of a form of rubber that tends to break down over time. As for the filter material, we offer both an oiled and a dry filter media. They both filter down to 3 microns (independently tested and verified) and flow virtually the same (within about 5% of one another). Really which one is better is a matter of personal preference. I generally recommend an oiled filter in very dusty off-road environments simply because the oiled filter will go longer between cleanings. The filter used with the full intake system flows over 1400 cfm.
Now, as for a full intake system versus a drop-in filter, they're not really designed to do the same things. The drop-in filter improves airflow over the stock filter and is cleanable and reusable (which adds convenience), while the full intake system frees up flow not just at the filter, but also in the rest of the intake system. Our MXP intake box has a large cold air scoop and seals against the underside of the hood to keep engine compartment air away from the filter. The intake tube is designed to further maximize airflow. Think of it as convenience and efficiency improvements with the drop-in filter, and efficiency plus performance with the full intake system. Both are good, it just depends on what's more imortant to you. The MXP Cold Air Intake system for the 6.0L has been dyno-tested to add 21 hp and 44 lb-ft of torque. We have probably more than 50 dyno pulls in our files for this kit, and those numbers are an average, not the best we got on an individual run.
Last but not least, all of our products are backed by a "No Hassle" lifetime warranty and are Made in the USA. Hope this helps!
